Question

Match List-I with List-II

List-I (Name of the Vitamin)	List-II (Functions)
(A) Vitamin A	(I) Promotes calcification of bone
(B) Vitamin D	(II) Promotes blood clotting
(C) Vitamin E	(III) Involved in physiology of vision
(D) Vitamin K	(IV) Functions as a biological antioxidant

Choose the correct answer from the options given below

• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (II), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Remember the functions of the fat-soluble vitamins:
- Vitamin A \(\rightarrow\) Vision.
- Vitamin D \(\rightarrow\) Bone calcification.
- Vitamin E \(\rightarrow\) Antioxidant.
- Vitamin K \(\rightarrow\) Blood clotting.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Vitamins are essential organic micronutrients required by the body for various metabolic and physiological functions.
They are classified into water-soluble and fat-soluble vitamins, with milk fat being a key source of the fat-soluble vitamins (A, D, E, and K).

Step 2: Detailed Explanation:
Let us match each fat-soluble vitamin in List-I with its primary physiological function in List-II:
-(A) Vitamin A (Retinol):
Vitamin A is essential for maintaining healthy vision.
It is a precursor for rhodopsin, the visual pigment in the retina required for low-light vision.
Therefore, (A) matches with (III).
-(B) Vitamin D (Calciferol):
Vitamin D regulates calcium and phosphorus absorption in the intestine.
It promotes the mineralization and calcification of bones, maintaining bone density and preventing rickets or osteomalacia.
Therefore, (B) matches with (I).
-(C) Vitamin E (Tocopherol):
Vitamin E is a potent fat-soluble antioxidant.
It protects cell membranes and lipids (including milk lipids) from oxidative damage by scavenging free radicals and stopping lipid peroxidation.
Therefore, (C) matches with (IV).
-(D) Vitamin K (Phylloquinone):
Vitamin K is a cofactor required for the synthesis of prothrombin and other coagulation factors in the liver.
It plays an essential role in the blood clotting cascade.
Therefore, (D) matches with (II).
This matching sequence corresponds to Option (A).

Step 3: Final Answer:
The correct matching sequence is (A) - (III), (B) - (I), (C) - (IV), (D) - (II).
